Effect of classic soft drink Coca-Cola as a solvent in the administration of tramadol and diazepam on biochemical and histological changes in liver and kidney
Abstract
The objective of this study was to determine the biochemical and morphological changes in the liver and kidney as a result of the acute administration of tramadol and diazepam with classic soft drink Coca-Cola (Coke ).
Method: Thirty-six (36) adult male Wistar rats were divided into six groups: Group A-control (distilled water), Group B (Coke ), Group C (tramadol, 50 mg/kg), Group D (tramadol dissolved in Coke, 50 mg/kg), Group E (diazepam, 10 mg/kg) and Group F (diazepam dissolved in Coke 10 mg/kg). All administrations were done intraperitoneal. Twenty-four hours after administration, blood samples were collected via cardiac puncture for evaluation of the liver (Aspartate aminotransferase [AST] and Alanine aminotransferase [ALT]), kidney (urea and creatinine [CREA]) function and the organs were excised and processed for histopathological examination.
Result: A significantly increased in AST, creatinine and urea concentrations was observed in Tramadol and Coke Groups compared to control (P<0.05), while diazepam had no significant effect on AST, ALT (P>0.05), though it caused a significant increase in urea and CREA (P<0.05). Dissolving the tramadol in Coke aggravated its hepatotoxicity and nephrotoxicity, while Coke had no significant effect on diazepam. Histological examination also corroborated the biochemical result.
Conclusion: The results showed that mixing drugs with Coke does not improve the toxicity of tramadol and has no significant effect on diazepam.
